Auto status back: a feature that allows the printer to send status
information back to the host computer automatically.
Two-way communication between the host and printer, which allows
the printer to return status information to the host. The IEEE-1284 standard
for the parallel interface has the capacity for bi-directional
communication. (See IEEE-1284.)
A graphic or a character comprised of individual pixels or dots. Bitmaps
are somewhat limited as to the degree to which they can be enlarged.
(See vector.)
A memory area in the printer that holds incoming data from the host
computer and processed in the order received.
Characters per line.
A test mode in which the printer prints hexadecimal numbers
representing characters and codes.
The standard used for the TM-L90 parallel interface. This type of interface
allows both bi-directional communications and unidirectional
("compatibility mode") communications.
Lines per second.
TheTM-L90 maintenance counters provide information that can be
retrieved remotely.
Non-volatile, flash memory. The data stored in this type of memory is not
lost when the power is turned off. The TM-L90's NV memory is used to
store graphics, primarily bitmap logos. (See bitmap.)
In this mode, the printer collects data and formatting commands in its
buffer until printing is specified with the ESC FF or FF command. This
mode gives the printer more flexibility in formatting, so that it can print
character and bar code data, or other graphics data, on the same line.
Most EPSON printer autocutters leave one point (small segment) of the
receipt uncut.
The maximum printable area.
The standard serial interface available.
